I have problems with audio transcoding in files with with the EAC3 codec sound. If I play in PC, or mobile Android or cast from android mobile to chromecast, plays perfect. But If I try to play directly in Chromecast TV, it´s stuck loading and not begin to play. The expected it´s direct play video and audio transcoding from EAC3 to OPUS.
I understand that it doesn’t do direct play because the device connected with ChromecastTV doesn’t support the EAC3 codec, but it doesn’t even start transcoding.
The funny thing is that there is an alternative solution, which is to perform the following steps:
- I change the video quality and hit convert to HD (with any bitrate, 720p for example)
- The movie starts playing by transcoding audio and video (with hardware transcoding)
- I change the video quality again and hit play in original quality
- The movie now plays correctly by transcoding only the audio and with direct play video, just as it should have done from the beginning.
It’s a bit of a pain to have to do this every time there is a file with this audio…
I checked the transcoder process inside container and it´s different when stuck loading and when plays fine transcoding audio. It seems that when it gets stuck, it doesn’t detect the segment format well.
The first time it plays the file when it gets stuck loading, checking the processes I see the following:

Once I change the video quality to 720p and return to original quality, where it does play correctly, I see the following process:

Finally, I have a CPU graph with the entire process:
Any idea?
Thank you!
