How to comvert MOV to MP4 with metadata [closed]

log (the input is different then in the screenshot) :
ffmpeg -y -i "/storage/9C33-6BBD/DCIM/×¢×™× ×‘/IMG_5267.MOV" -c:v libx265 -q:v 5 -c:a aac -ab 128k -ar 44100 "/storage/emulated/0/FFMPEG/IMG_5267.mp4"

How can I mux (or encapsulate) H.264 RTP output into a container using FFMPEG ?
7 octobre 2013, par GradI am working on the effects of network losses in video transmission. In order to simulate the network losses I use a simple program which drops random RTP packets from the output of H.264 RTP encoding.
I use Joint Model (JM) 14.2 in order to encode the video. However, I don't use AnnexB format as my output, instead I choose the output as RTP packets. The JM output is generated as RTP packets with RTP headers and payload as a sequence. After that, some of RTP packets are dropped by using a simple program. Then, I can decode the output bitstream by using also JM and it's error concealment methods.
The main purpose of this process is to evaluate the differences created by network losses on the human video quality perception. In order to measure the perceived quality, the shown video must be in its decoded form (i.e. full resolution) or it can be decodable at the receiver side. The RTP packets created by the JM Encoder cannot be decoded without the JM software installed. However, with the proper header (or container) most video players are able to decode the bitstream. So, the my goal in this question is to encapsulate my encoded RTP packet bitstream in a common container such as AVI or MP4 to have my content decodable at the receiver computer.
The format of the encoded bitstream in RTP packetized form is as follows :
----------------------------------------------------------------------
| RTP Header #1 | RTP Payload #1 | RTP Header #2 | RTP Payload #2 |...
----------------------------------------------------------------------In order to find the video quality, I want to make a subjective test with these bitstreams. I can make these test by using the full resolution data decoded by myself whereas it's very inconvenient to crowdsource this subjective test with GBs of video data on the Internet. So, I want to mux these bitstreams into a container (i.e. AVI) by using FFMPEG. I have tried to decode these bitstreams with FFMPEG and FFPLAY ; however, both of them didn't work. I also tried the following command and it didn't work, either.
ffmpeg - f h264 -i -vcodec copy -r 25 out.aviWhich format or muxer should I use ? Do I need to convert these files to any other format ?
